FAQ

Frequently asked questions

How does the tool identify broken links in my HTML?

The checker parses your HTML code, extracts all links, and validates their format (protocol, structure, syntax). It flags links with invalid syntax, missing protocols, or obvious formatting errors instantly.

What's the difference between 404 errors and broken anchor tags?

404 errors occur when a server can't find the page (active link to non-existent URL). Broken anchor tags are malformed HTML links (missing href, bad syntax). This tool detects both types of issues.

Will fixing broken links improve my search engine rankings?

Yes. Fixing broken links improves user experience, reduces crawl errors, and helps Google crawl your site more effectively. Fresh, valid link structure is a positive SEO signal.

Can I batch check links from multiple pages?

Paste the HTML from each page separately or combine multiple pages' HTML in one input to check all links at once. The tool will analyze all links in the provided code.
